SPECIFICATION forming part of Letters Patent'No. 783,164, dated February21 1905.

Application filed July 22, 1904. Serial No. 217,633. I

To all whom it may concern.-

Be it known that I, ADAM WOELFEL. a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Windows; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to. a novel construction in a window, the objectbein to provide a device of this character in which the sashes may beturned inwardly for the purpose of easily washing the panes on theirinner and outer faces; and it consists in the features of constructionand combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 isaview in elevation, partly in longitudinal section, of a windowconstructed in accordance with my invention. Fig. 2 is a detail plansection, on an enlarged scale, on the line 2 2 of'Fig. 1, both the upperand lower sashes being shown at the lower limit of their movement andswung open. Fig. 3 is a fragmentary detail plan section, on an enlargedscale, on the line 3 3 of Fig. 1, the lower sash being removed.

I am aware that windows have been constructed which are operated on thesame general principle as in my invention; but the construction thereof,so far as I have been informed, has been complicated or objectionablefor other reasons.

In windows it is generally desirable that all fixtures should beinvisible as far as possible,

' for the reason that the exposure of too much hardware is usuallyobjectionable. It is also desirable that the operation of the sameshould be as simple and efiicient as possible, and to these ends mydevice consists in mounting in the guides A and B between theblind-stops C plates D, each provided between its ends with a pivot fora plate E, which is provided with an inclined slot F and is adapted tobe turned up and be received in a recess G of said plates D out of thepath of each of the sashes H and J. The said plates D are disposedbetween the limits of movement of said sashes and a distance about equalto the length of each sash. Said plates E are so hinged to the plates Dthat when the same are turned down they are limited in their movement,so that they cannot be turned farther than a horizontal position. In thelower end of each sash in vertical alinement with the inner end of theslot in each of said plates E, I provide a pin K, and in the upper endof each sash in vertical alinement with the inner end of each slot ofthe upper plates I provide a projection L, having an enlarged head M. Asection end of each of the inner blind-stops on that side of the frameopposite to that on which the plates are mounted is made removable inany convenient manner.

My device is operated asfollows: When it is desired to clean thewindows, the lower sash is first raised to a position about the upperend of the lowermost plate D, and the plate E pivoted thereto is thenturned down, as is also the corresponding plate E, mounted in the outerguide. The lower sash is then lowered until the pin at the lower end ofsame enters the said slot in said lower plate E, and. the upper plate Eis then turned down, and thus inserted over the top projection L. Theremovable section of the inner blind-stop is then removed and the saidsash turned inwardly until the cord is exposed. The latter is providedwith a ring O at its end, which is inserted over a hook P in said sashand is removed and inserted over a hook Q, provided therefor on theframe. Said sash may be freely turned on its pivot, so as to enable theouter face of the pane to be easily cleaned, and in turning same thesaid pin and. projection at the lower and upper ends of said sash willmove to the outer ends of the slots. The slot in the upper plate E is ofless width than the head M of said projection except at its inner end,so that after said projection enters the outer end portion of said slotit is practically locked in position. The slot in the lower plate Eextends at a greater incline, and its inner end is deflected inwardly,so as to form a pocket R in which the pin on the lower end of the sashis received, so as to bring said pin in vertical alinement with saidprojection L and hold same against longitudinal movement in the saidslot. To turn the outersash,

the operation is substantially the same, the lower plate E being turneddown, the outer sash then lowered, and the upper plate being then turneddown in the same manner. The removable section of the blind-stop is thentaken out and said outer and upper sash turned inwardly until thesash-cord is exposed and disconnected therefrom. The said outer sashcannot be turned quite as far as the inner sash, for the reason that thelatter remains partly in its pivot, and to enable the same to .be turnedsufliciently inwardly to enable easy access to the outer face of thepane the plates E supporting the said outer sash are made of greaterlength than the plates E supporting said fixtures may be easily appliedto old windows as well as new.

I claim as my invention A window comprising a frame and sashesvertically movable in guides in said frame, the blind-stops at one sideof said frame being partly removable, two plates disposed in each of theguides at the other side of said frame between the limits of movement ofsaid sashes and at a distance apart equal to the length of the latter, aleaf pivotally mounted on each of said plates and movable through an arcof ninety degrees, said plates being provided with recesses to receivesaid leaves and retain same out of the paths of the sashes when not inuse, each of the leaves of the upper plates being provided with aninclined slot enlarged at its inner end, and each of the leaves of thelower plates being provided with a slot disposed at a different anglethan the slots of the leaves of said upper plates and being deflectedoutwardly at their outer ends, thus forming recesses disposed invertical alinement' with the inner ends of the slots of the upperleaves, a pin on the lower end of each sash adapted to enter the innerends of the slots of the lower leaves, and a projection on the upper endof each sash, having an enlarged head adapted to enter the enlargedinner ends of the slots of the upper leaves, said pins and projectionsbeing adapted to move to the outer ends of said slots when the sashesare turned, substantially as described.

In testimony whereofl have signed my name in presence of two subscribingwitnesses.

ADAM WVOELFEL.
